Rsync :: Pull The Data From ServerA To ServerB
Feb 27, 2008
Trying to figure out rsync and am a little confused. Here is what I am trying to accomplish (usernames, passwords, and Ip's changed to protect the innocent):
ServerA = Live production server
ServerA Username = rootA
ServerA Password = passwordA
ServerA IP = 123.111.222.AAA
Directories from ServerA to backup: /usr/home/www and /var/lib/mysql
ServerB = Backup server
ServerB Username = rootB
ServerB Password = passwordB
ServerB IP = 123.111.222.BBB
Location on ServerB where backups will be located: /usr/BACKUPS
rsync is located on ServerB at /usr/bin/rsync
I want to use ServerB to pull the data from ServerA to ServerB. I want to maintain all permissions, ownerships, etc. I will be putting this in a cronjob to run every 48hours. After the rsync is done, I would like to see the following on ServerB:
/usr/BACKUPS/www
/usr/BACKUPS/mysql
Is this possible? And if so, what command usage would I use? And how would the password get passed?

I tried also to run it manually but there is an error.Command:
#rsync -avz --exclude=/proc --exclude=/backup -e ssh / user@user.bqbackup.comerver1
The error:

multiplexing overflow 1:1075
rsync error: error in rsync protocol data stream (code 12) at io.c(681)
What should that be ? I didn't change anything in my server ...

I am putting this thread to take other people advise and to advise them about my bad experience with rsync. Lucky, I was able to get my data back through the old drive
Three times a day, I take mysqldump and then rsync that mysql dump to a drive located in a different state.
Everything was working fine..The rsync was transferring data daily and updating the backup on other server. Few days ago, there was a hard drive failure on my server and then i checked in my backup drive for mysql dump...It was 764 bytes instead of 5 Gb...
Then i went to my other server where I rsync, to my surprise that was also 764 bytes from 5 Gb as it synced the both database..
My backup strategy failed and would be in tears if I couldn't grap data from failed drive
I would like to hear everyone views on this and learn from it

Is there anything better then rsync to replicate files (twice a day) on servers located in seperate datacenters?
Looking for more of a free to cheap solution though will also be interested in the higher end solutions later on.

Does rsync required to be installed on both servers for it to work? Can rsync work with ftp only on the remote server?
Can you guys list some typical rsync shell command to help me get started...

I am using BQbackup to auto backup my CPanel VPS and was wondering whether it is best to use CPanel's own backup service which automatically backs-up the vps daily or should I use the rsync script that bqbackup provides?
Which is easier to restore and more reliable?

Looking for an RSYNC tutorial, something that focuses on backing http data, exporting the databases then transferring offsite to a receiving rsync server once a week.
Something that's understandable and logical would be great, happy to work through over the next week and continue more in depth with it.

I have been trying to setup rsync on my server and following these instructions
http://www.bqbackup.com/setup.html
The problem is I keep getting errors.
On this step,
ssh-keygen -t rsa -N
I edited it and did ssh-keygen -t rsa --N becauseI got an error saying it need the '--' before the N.
So after getting through that part, I got these questions asked
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
I left the passphrase empty, and then when it asked where to save to, I just typed in 'rsa'. Then it gave me some fingerprint.
Then I get to the step,
# scp ~/.ssh/id_rsa.pub yourusername@yourusername.bqbackup.com:keys/server1
# ssh yourusername@yourusername.bqbackup.com mergekeys
But I get errors saying
-bash: cat~/.ssh/id_rsa.pub: No such file or directory
I dont get what I'm doing wrong. If somebody doesnt mind, can you please re-write the steps on getting this working, or maybe tell me where I am going wrong if the tutorial is correct?

one day later, if I run the following command again, the command is same as the one run by the first time.
rsync -avz username@IP:/home/asite/public_html/ /home/asite/public_html/
does it mean rsync will just check and copy the newer folders and files from the last copy?

I have a bit of a strange problem, I have an rsync command setup in the servers crontab and from the cron log it show it ran the command but the files don't copy to the backup server. If I take the rsync syntax and run it manually all the files copy across with no errors, but I can't figure out why the cronjob doesn't work properly.

I'm trying to configure rsync to backup my vps data to an rsync backup provider.
The problem that I am having is that each time I try to run rsync it prompts for the passphrase.
I did some reading and it seems (and maybe this is not correct), that in order to do unattended rsync (e.g. using cron), that you need to use a key that doesn't have a passphrase generated.
If this is the case, is it true that it's not a good idea to use a key that doesn't have a passphrase?

I got one of those cheap $10 servers from hostmds to use to backup my vps.
Know I just need to know how do I setup rsync to backup my vps nightly? Any links to good guides to do this would be great. I looked on google, but am hoping someobody knows a guide that is simple to follow.

I am in the process of setting up a cronjob so I can run rsync automatically every day.
But I want to know is it ok to exclude the following folders?
/home/.cpcpan/
/home/cpeasyapache/
/home/src/ <!--- This folder I made to put files in before I install
/home/MySQL-install/
/home/.cpan/
As from what I understand cPanel/WHM makes these folders, and there no user data in these folders

I have wrote a small script which copies file names which has name as *default* from backup to users main folder. It works fine with one folder but doesn't copy files from sub-folders.
it works with all the sub-folders as well?
HTML Code:
#!/bin/bash
for i in $(ls /var/cpanel/users)
do
rsync -vrplogDtH /backup/cpbackup/weekly/$i/homedir/public_html/*default* /home/$i/public_html
chown -R $i.$i /home/$i/public_html/*default*
done

FTP backups, doing RSYNC what is needed?
I have a linux box with pure-ftpd as FTP backup server. However, we want to explore/expand to RSYNC now.
Is there a package that allows RSYNC to be used for FTP users?
This is basically like what do FTP services like BQbackup use to allow RSYNC, etc.

I just signed up with Rsync Palace for remote backups 2 days ago. Otto and Darin at Rsync Palace gladly helped me out and actually ended up setting me up for free. It's really an inexpensive price to pay for a little additional piece of mind to have a remote backup.
I have a VPS with cPanel that has NAS on a private network. The way they set it up was for Cpanel cron job to create backups of my VPS and place the backups in a /backup folder off root; Daily, Weekly and Monthly.
Then they have Rsync via cron set up to take those backups to the remote Rsync Palace server daily.
I still want to maintain backups on my NAS in the datacenter. (cPanel will only backup remotely or locally, but not both.)
In addition to Rsync securely transferring my data to Rsync Palace for offsite backups... How can I set up Rsync to ftp the same /backup data across the private network to the NAS? (Only ftp is available via the NAS.)

I use bqbackup.com in addition to ServInt's backup. The ServInt backup is inaccessible to me and can be restored only by their NoC.
Is there a way for me to download the backup files from bqbackup.com to my PC? I am using Win XP Pro. I backup the entire VPS, but I want to be downloading only the changes made each day after the initial download to my PC.

I am trying to recover some backups on the server by rsync the home dir from BQbackup to my server. I deleted 1 file to see whether it actually works. I executing this command on the server:
rsync -avz -e ssh username@username.bqbackup.com:path.to.home.dir /home
I saw that it downloaded the file I deleted, however after checking on FTP if the file was recovered it actually wasn't. Is there something wrong in the command I used as it seems that it is not recovering any files.

I am setting up a mirror server to kick on in the event my main server fails and I need some help with syncing the two.
It is my understanding I can use rsync to mirror the two. But, will that cover everything (ie. database, mail, etc) or only files?
